Summary of the invention
The object of the present invention is to provide a kind of nickel-coated steel coin and manufacture craft thereof of applying lines and combining meticulous figure line technology, after enforcement, popular anti-counterfeiting performance and the appearance of nicke-clad steel material coin are all promoted largely.
The object of the present invention is achieved like this:
Have the nickel-coated steel coin that lines combine meticulous figure line, this coin is steel core nickel plating material, and the figure line on coin forms by putting with line, can observe the different-effect of coin figure line in different angles; The figure line of described point and line composition is stealth, embossment or micro pattern.
The manufacture craft of above-mentioned nickel-coated steel coin comprises following idiographic flow:
A) design drawing line, adopts SCD version line design system software that figure line is expressed by point and line, and point is 0.01～1mm with the width of line, and point is 0.01～1mm with the spacing of line;
B) adopt CAM engraving software to convert the figure line through process of refinement to engraving file, the carving depth of set-point and line is 0.01～0.06mm;
C) adopt computer engraving machine or laser engraving machine engraving grand master pattern, adopt the mode repeatedly turning over to turn over die, on base cake, impress the nickel-coated steel coin of providing lines and combine meticulous figure line by marking press.
Accompanying drawing explanation
Fig. 1 is fabrication processing figure of the present invention;
Fig. 2 is coin schematic diagram of the present invention;
Fig. 3 is that mould of the present invention turns over location schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Make coin of the present invention by the location schematic diagram that turns over shown in the flow process of Fig. 1 and Fig. 3:
1) the figure line by meticulous figure line SCD version line design system, coin being designed on picture proof is expressed with point and line, and the width of set point and line is 0.01～1mm, and the oblique angle of line is 0～180o, and the spacing of point and line or etween the lines is 0.01～1mm.
2) convert the figure line through process of refinement to engraving file by Artcam software, the carving depth of set point and line is 0.01～0.06mm simultaneously.
3) engraving file is imported in computer engraving machine or laser engraving machine and carries out grand master pattern engraving.
4) because the hardness of nicke-clad steel material is higher, in moulding process, point wants large with distortion compared to other coin material with the loss of line, in order to reduce loss and the distortion of meticulous figure line in moulding process, adopt the mode repeatedly turning over to turn over die, there is not loss in the degree of depth of guaranteeing meticulous figure line on die and figure line does not deform, specifically the die after once turning over is carried out to vacuum softening annealing, its annealing process is: vacuum drying oven is heated to 860 ℃, be incubated 2 hours, then cool to room temperature with the furnace.To reduce the die of hardness again again with turning over once after grand master pattern aligned pattern, there are lines to combine the nickel-coated steel coin figure line degree of depth of meticulous figure line more shallow due to a kind of, therefore, turn in process at secondary, figure line contraposition on figure line and grand master pattern on die is difficulty comparatively, for guaranteeing again to turn in process, there is not deviation in the figure line on die, in the time turning over for the first time, on grand master pattern, having set five positioning ports positions, die after once turning over is after soft annealing like this, carrying out secondary while turning over, grand master pattern just can overlap completely with the figure line on die.After secondary turns over, the upper figure line of die is more clear full like this, and the loss of meticulous figure line is less with distortion, can guarantee like this definition of meticulous figure line on nicke-clad steel product.
